Do any of the Adobe Creative Suite 5 or CS5.5 applications require updates to be compatible with Mac OS X Lion?
At this time, none of the CS5 or CS5.5 applications require updates to be compatible with Lion. However, we do recommend that all users download the latest version of the Adobe Flash® Player runtime (version 10.3). We encourage our customers to review other documented issues and information regarding updates in the Mac OS X Lion Knowledgebase article.
